These are just ideas to help you get inspiration from. Some of the brand's may not be the ones I would personally choose, just the ones who's product looks best, more research might be needed as more recent or better quality products may exist.
"A gift voucher is kind of like giving money but it shows that you know the person. It could be a voucher to their favourite cafe, bookstore, spa, hairdresser, shop... Make sure to check the average price of goods in the store before putting some cash to avoid bad surprises from the giftee."
"The least you could do if you have no idea what to get someone is to write them a card. Maybe tell them how much they changed your life, how happy they make you, tell them about all the things you can't wait to do with them. Maybe slip some cash in it as well, always makes someone smile 😂🌚 "
"These bracelets can be personalized via charms. Pandora has a wide variety of them for all occasions and tastes. I have mine for at least 6 years and I love it, every charm holds a dear memory and they make great gifts ! "
"If you are live in a different country or the person you are giving the gift to is foreign then a hamper with the local goodies is always a great way to help them discover the culture. This can be done for all types of things, from art supplies to skin care products. Choose size/price accordingly."
